scipy.linalg.lapack.dpotri#
- scipy.linalg.lapack.dpotri(c, lower=0, overwrite_c=0) = <flapack function dpotri>#
Invert a positive definite matrix from the factorization computed by
potrf(LAPACKdpotri).- Parameters:
- cndarray
Cholesky factor, as returned by
potrf.- lowerint, optional
If nonzero, c is the lower triangular factor; otherwise the upper. Must match what was passed to
potrf. Default is 0.- overwrite_cint, optional
If nonzero, c may be overwritten in place. Default is 0.
- Returns:
- inv_andarray
The inverse, stored in the selected triangle only; the opposite triangle is left as it was in c.
- infoint
0 on success; if negative, the
-info-th argument had an illegal value; if positive,c[info-1, info-1]is zero and the inverse does not exist.
